IMPROVEMENT IN MEASURE-FAUCETS Specification forming part of LettersPatent No. 39,654, dated August 25, 1863 To all whom, it may concern.-

Be it known that I, GILBERT HUBBARD, of Sandisfield, in the county ofBerkshire and State of Massachusetts, have invented a new and ImprovedlVIeasure-Faucet; and I do here by declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in whichFigure l is a side View of my invention; Fig. 2, a vertical longitudinalsection of the same, taken in the line 00 m, Fig. 3; Fig. 3, a plan ortop view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in the employment or use of a rotating slidingpiston placed withiu'a chamber which is in communication with the tubeof the faucet, the piston being fitted within a head provided with avalve, and

having at one end of it, outside of the chamber, a wheel provided with atooth, which engages with a toothed index-wheel, all being arranged insuch a manner that liquids may be drawn by measurement from a cask orreservoir, the flow of the liquid ceasing when the desired quantity isdrawn.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a chamber, which is slightly of elliptical form, andcommunicates with a tube, B, at a, and with another tube, 0, at a, asshown in Fig. 2. The tube B is inserted in the cask or barrel from whichthe liquid is to be drawn, and O is the tube from which the liquid isdischarged, and all the liquid which passes through the faucet passesthrough the chamber A.

D is a shaft, which is fitted transversely in the chamber A, and isallowed to rotate freely therein. The bearings of the axis 1) of theshaft D are in the sides of the chamber A, and in the shaft- D there isfitted a sliding piston, E, both ends of which are in contact with theinner side of the chamber A at all points in the rotation of the former,the piston E sliding as the shaft D rotates. The shaft D is placedmidway between and in line with the openings a a, and in contact withthe upper part of the chamber A, to serve as a cut off, as shown in Fig.2.

To one end of the axis 1) of the shaft D there is attached a smallwheel, F, which is provided with a single tooth, c. This wheel F is atthe outer side of the chamber A, and there is also a large wheel, G, atthe outer side of the chamber A, said wheel being fitted loosely on afixed shaft, H, having a spiral spring, d, upon it, the inner end ofwhich bears againstthe wheel G, and the outer end against a nut or.head, 0, on the outer end of shaft H. This spring 61 prevents the wheelG from casually moving or turning as it presses it against a circular.fixed plate, f, at the outer side of chamber A. (See Fig. 3.)

To this wheel G there is attached an index, 9, which projects a shortdistance beyond the periphery of the wheel G and to the outer side ofthe chamber A a small pin or projec tion, h, which serves as a stop forthe index 9 to come in contact with, and thereby arrest the motion ofwheel G and the shaft D. The tooth c of the small wheel F engages withthe teeth of wheel G, and at every revolution turns the wheel G thedistance of one tooth.

I represents a valve, which is provided with a stem, J, that is fittedand allowed to slide freely in the shaft D. The opening in which thestem is fitted and works passes transversely and entirely through shaftD, as shown in Fig. 2, and said valve, when closed, fits within a recessin the shaft D. When the liquid is running through thefaucet, it passesthrough the tube B into the chamber A, as

indicated by the arrows 1, and acts against the piston E, forcing itaround and filling the chamber back of the piston, and when the pistonhas'made one-half of a revolution and reaches the position, as indicatedin red, one end of the piston will have passed the opening a of tube B,and the liquid from B will act against the opposite side of the piston,which still rotates, and the water which previously entered chamber A,and is in front of the piston, will be forced through opening a and intoand out of tube 0, as indicated by the arrows 2. At every revolution ofshaft D the wheel G is moved the distance of one tooth, in consequenoeofthe tooth c of the wheel F engaging with it, as previously described,and the liquid willcontinue to run and be discharged until the wheel Gis arrested and stopped, which is done by the pin or stop h. In order,therefore, to draw the reqniredamountiotiliquid, the wheel G is set atthe commencement so that its index 9 will be at the proper distance fromthe stop h. The proper setting of the wheel G is accomplished by havingthe outer side of the chamber A graduated,-as shown at a Fig. 1. Thismay be accurately done, the capacity of the chamber A being known, andconsequently the amount of liquid discharged at. each revolution of thepiston. The wheel G may be turned by drawing it outward from the side ofthe chamber, so that it will be free from the tooth c of the wheel F.The piston E is always stopped at the same point or in the sameposition, which is indicated in red in Fig. 2, and-when the piston isstopped the valve I, underthe pressure of water behind it, whichpassesthrough the opening in which the stem J works is forced or pressedover the opening aof, the. tube B, and as soon as thisopeningclosestheuflow of water ceases, as,

there is-no. escape for itfrom chamber A, and there .islan equalpressure on each side of shaft Dr Whenthe wheel Grv is; set to draw thedesigned quantity of 1iquid,-;itzis turned a little, so thatethe valve Iwill be moved past the openingaa, and the flow then immediatelycommencesland continues until thepiston is stopped by the index 9 ofwheel G coming inicontact with the stop h.

I would remark that the valve I may be assisted in its operation by aspring so applied as to have a tendency to keep the valve in a recess inthe shaft D but it will operate very well without, the pressure of thewater effecting that result.

Havingthus described my invention, what claim as new, and desire tosecure by Letters Patent, is-- 1. The chamber A, communicating with thetubes B G, and provided with the rotating sliding piston E and valve 1',all arranged to operate as and for the purpose herein set forth.

2. The wheels F G, in combination with the rotating sliding piston E andvalve I, placed within the chamber A, the wheel F being provided with asingle tooth, c, which engages with the wheel G, and the latter providedwith an index, g, which comes in contact with a stop, h,'at the side ofthe chamber A, all being arranged substantially as and for the purposespecified.
